Abstract

Tantangan dalam membangkitkan tenaga listrik untuk memenuhi kebutuhan beban dan regulasi untuk menurunkan tingkat emisi karbon dioksida (CO2) merupakan faktor utama yang mendorong energi baru dan terbarukan (EBT) terus berkembang dalam beberapa tahun terakhir. Dari berbagai bentuk teknologi energi baru dan terbarukan, photovoltaic (PV) merupakan jenis teknologi yang sering digunakan. Harga investasi yang lebih rendah daripada pembangkit EBT lainnya, ukurannya yang fleksibel, dan tidak memerlukan maintenance yang kompleks menjadikan PV banyak dipilih sebagai pembangkit EBT sebagaimana bisa terlihat pada rooftop atau Pembangkit Listrik Tenaga Surya (PLTS). Hingga saat ini, sistem PLTS terhubung langsung dengan jaringan distribusi. Bertambahnya PLTS pada jaringan distribusi dapat memberikan manfaat terhadap sistem dalam mengurangi losses daya aktif dan daya reaktif. Tetapi, penetrasi PLTS kepada grid yang terlalu tinggi akan memberikan perubahan secara signifikan pada sistem sehingga menyebabkan sistem keluar dari batas stabil. Oleh karena itu, diperlukan keseimbangan antara daya beban dan daya suplai agar frekuensi dan tegangan sistem dapat tetap terjaga pada batas normalnya. Menurut RUPTL 2021-2030, akan direncanakan pengembangan pembangkit PLTS dengan kapasitas 5 MW di Pulau Bawean sehingga diperlukan antisipasi agar sistem PLTS yang nantinya akan terinterkoneksi dengan sistem eksisting tidak mengganggu kestabilan keseluruhan sistem. Model sistem kelistirikan akan disimulasikan menggunakan software ETAP (Electrical Transient Analysis Program) versi 19.0.1 dengan studi kasus lepasnya beban dengan kapasitas besar mempertimbangkan level penetrasi PLTS.

Challenges in generating electricity to meet load requirements and regulations to reduce carbon dioxide (CO2) emission levels are the main factors driving new and renewable energy (EBT) to continue to develop in recent years. From the various forms of new and renewable energy technologies, photovoltaic (PV) is the most used technology. The investment price is lower than other EBT generators, flexible in size, and does not require complex maintenance, making PV the preferred choice for EBT generators, as can be seen on rooftops or Solar Power Plants (PLTS). Until now, the PV Plant is directly connected to the distribution network. Increasing PV Plant connection in the distribution network can provide benefits to the system in reducing losses of active power and reactive power. However, the penetration of PV Plant to the grid that is too high will give a significant change to the system causing the system to go out of stable limits. Therefore, a balance between load power and supply power is needed so that the frequency and voltage system can be maintained at normal limits. According to RUPTL 2021-2030, there is a plan to develop a PV Plant with a capacity of 5 MW on Bawean Island. Hence planning is needed so that the PV Plant system that will be interconnected with the existing system does not disturb the stability of the entire systems. The electrical system model will be simulated using ETAP (Electrical Transient Analysis Program) software version 19.0.1 with study case in the form of load reject with large capacity with different scanarios of level PV penetration.
